Abstract

PCT No. PCT/EP95/02794 Sec. 371 Date Mar. 26, 1997 Sec. 102(e) Date Mar. 26, 1997 PCT Filed Jul. 17, 1995 PCT Pub. No. WO96/04084 PCT Pub. Date Feb. 15, 1996The press comprises two tool holders facing each other (28a, 28b), capable of relative movement one towards the other and back again. Each tool holder carries a bending tool (40a, 40b) and a clamping tool (42a, 42b). The tool holders (28a, 28b) are in addition capable of relative movement between two working positions in one of which the rear edge (46a) of a tool holder (28a) is so positioned as to cooperate, in order to bend the sheet (L) in a first direction, with a front edge (44b) of the bending tool (40b) of the other tool holder (28b), and the clamping tool (42b) of the other tool holder (28b) is immediately opposite the tool of the first tool holder (28a) in order to cooperate with it through the interposed sheet (L). In the other working position, the functions of the edges of the bending tools and the functions of the clamping tools are reversed in order to carry out the bend in the other direction. The clamping tools (42a, 42b) are mounted in their tool holders in such a way that they retreat against the force of means of elastic repulsion (50a, 50b).
